When you cast an object in resin it will either come out clear or white, depending on the kind of resin you use. Although you can add dyes to the liquid resin while casting to achieve chromatic colours, you have to use a powder such as bronzing powder to achieve metallic colours. You can also use it with other craft projects either on its own or mixed with mediums such as polymer clays and paints.

  1. 1

    Bronze moulded resin figures while you cast them by mixing the bronzing powder into the liquid resin. The exact amount you should use depends on how rich a colour you want. You can then pour the bronzed liquid resin into a mould and allow it to cure.

  2. 2

    Brush moulds with bronzing powder if you wish to conserve the amount of powder you use. When you pour the liquid resin into the mould and allow it to cure, the powder will become fixed to the surface of your resin item.

  3. 3

    Bronze a sculpted object by mixing bronzing powder into the sculpting material such as polymer clays and epoxy based putty. You can also use moulds with many of these sculpting materials, but you will need to coat the moulds in a release agent to make sure they do not stick. For this reason you cannot use the brush-bronzing method with these materials.

  4. 4

    Use bronzing powders with paint to coat the outside of a piece of art. Simply prime the art using a brush-on or spray primer. Then mix the powder in with the paint and apply it to the object. You can use the paint to adjust the tint and hue of the bronze effect.

  5. 5

    Brush the bronzing powder directly on to an object and get it to stick by spraying the piece down with acrylic sealant. Do this in a ventilated area with a dust sheet.

Tips and warnings

  • You can get a fine sheen by lightly running a souring pad over the bronzed surface.
  • Wear a dust mask and gloves when working with bronzing powder.
